To all whom,4 it may concern Be it known that I, CHARLES M. 'A Bno'rr, a citizen of the United States, residing at Watertown, county of Middlesex, Common- Wealth of Massachusetts, have invented cer- Atain new and useful Improvements 1n Methods of Treating` Bundles of Shingles, of which the following is a specification.

This invention relates to the coating or impregnating of shingles, or like articles, in the bundle.

The application of creosote, or any similar preservative, paint or stain, to shingles has been usually accomplished by dipping' or brushing individual shingles in order to give This,"

to them a uniformity of treatment. of course, has resulted 1n considerable eX- pense on account of the time'and labor necessary for handling, and also in a considerable Waste of material due to the detailed appli-l cation of it to the many parts.

It is the object of my present invention to provide for the treatment of such articles in` the same being offered as an illustrative eX-- ample of a practical employment of my My invention may be practised with the aid of various mechanical devices of more or less complexity.

For the purpose of further describing the successful practise,of my method I have shown in. the accompanying drawing-s a simple device which have found in the further stages of Inyinvention to be of high practical eiiciency. l It will be understood that theV device shown in these drawings and hereinafter described is used merely as an illustrativeshowing of the steps of the method.. l

Through-out specification and drawings like referencek numerals alie employed to indicate correspondng parts and in these drawings v Figure l is a side view of the illustrative.

machine with the tank partly broken' away to expose the, interior, Fig. 2 isl a sectional view of a tank showing the cage' elevated in horizontal or operative position and also indicated in dotted lines in vertical or dipping position,-Fig. 8 xshows the cageI submerged, and Fig. 4. is a mere illustration of a sectional bunch of shingles illustrating the shingle layers.. A

. A bunch of shingles, as is'well known, is laid up in a pairof piles disposed with their `weather ends outward and the thin tapered tips inward, and alternately interposed. The bundles are bound, usually in the center, by some convenient clamping means, as by a pair of splints corded at their ends.v The center of a bunch of shingles iSVtherefore, laminated. When observed edgewise it will be seen that. due to the alternation of the tips, transverse. spaces are left extending crosswise of the bunch. These spaces grow less and less toward the ends of the bunch where the thicker portions of the shingles are pressed together.

have found that by dipping the bunch laterally into a tank of creosote, or other treating liquid, that the liquid will penetrate the central portion of the bunch,A permitting the bubbles of air to rise vertically across the areas or spaces near the center of the bunch. lVhen dipped in this way the penetration of the liquidis very rapid and very even and the bunch takes up a considerable quantity vated from 4its rst position, in which the spaces are vertical, to a position in which the spacesare horizontal, the liquid will now find itself on surfaces which are substan.

tiallv level. These surfaces ha ve, however, a slight incline outwardly and, at the same time, the superimposed shingles whose surfaces inclose the 'space come together closer and closer toward the endof the bunch. It now` the bunch be rapidly rotated the liquid Wi-ll be driven outwardly with increasing force as it approaches the ends of the shingles. The distribution of the liquid will, therefore, be substantially uniform and vith a substantial tendency toward a delivery ot' the greater part of it lengthwise of the shingle and outthrough the closely laid butts at the ends`of the bunch. A

rhe rotation of the bunch is continued just long enough to secure a complete distribution of the liquid and an elimination of any excess material from the bunch. 'lhe centrifugal force acquired by the liquid overcomes the capillary attraction ot' the surface of the shingles, thus causing a uniform distribution ot the liquid. The rapidity with which the bundles may be dipped and rapidr`ity of the rotation to which they are. subjected depends somewhat on the, nature ot the liquid, and also upon the kind ot shingles. The centrifugal action oi the liquid within the bunch, however, is so romplete and uniform that the elimination of excess liquid is positively assured.

Referring to the accompanying drawing, which shows a simple form of the. device which I have found satisfactory iii-thc practical.. use of my invention, l have provided a tank 1 supported on a suitable apparatus 2 set on a. base The shaft 4 passes vertically through the bottom of the tanlt, leakage being prevented bya stalling' box (in the upper end of the shaft.- /l is a fork (l suitably notched, as at 7, and in the notch 7 rests the squared ends of journals 8 which are attached Ato a. cage 9 having a suitable top l0. 'lhe cage is also provided with e. handle 1l for the convenience of the ol'ierative in turning the cage within thefork. rl`he lower part of the shaft 4 has a pulley l2 on which a shal't is splined for vertical reeiprocation. This pulley furnishes a rotative tendency for the shaft 4. Midway of the shaft is a sleeve i3 supported through an intermediate ball race 14 on a collar l5. The collar lf3 has a roller stud 'i6 adapted to Work in the cam i7 controlled by the hand lever 18.

ln operating this device, in accordance. with my method, the power may be applied to the pulley l2 to rotate the shaft 4 so that the bunch et shingles placed within the rage i) will be rotatably revolved in a horizontal position. in this position, as hereinbefore explained, any staining or filling liquid which may be presented between the layers of shingles will be forced outward toward the butt of the shingles. evenly distributing the same and throwing ofi any eiceess which may have been acquired. The dipping of the shingle bunch is preferably accomplished by tipping the cagefrom a horizy ntal to a vertical position, as shown by dotted lines in Fig. Q. The cage is then submerged by throwing the lever 18 from the position shown in Fig. 1 to the left, thus lowering the shaft 4- until the cage is sub mergedbelow the liquid tank l. In approaching this position` the liquid rising edgewise through the shingle hunch will drive out the air and evenly distribute itself in the central part ot the'hunch. For this reason as soon as the hunch has been coinpletely sulnnergml it may he raised to the position shown in dotted lines in Fig. 2. after which the enge may lie lifted up and turned into the horizontal position. The piilley l2 may then be started and the bunch rotated spreading the slainer or filler evenly through the bunch. as described.

Various devices may obviously he employed to practise my invention and the method may be. practised with somewhat varied modifications in lhe manipulation and in the conditions, without rilq'iarting from the spirit oi inv invention it within the limits oi" the appended claims.

li'hat l therefore elairn ind desire to seeure h v Letters latent is:

i. 'l`he method ot treating shingles in the original compact bundles comprising the introduction oll the treating liquid within the transverse erevices formed by the laminatihns and subsequently rotating the bundle on an axis at right angles to the greater length of the shingles to uniformly distribute. the liquid along the surfaces ot the shingles in contact in the bundle and to eX- prl the exeess liquid therefrom.

The method ot treating shingles in the original compnet bundle comprising the. dipping ot the. bundle in the. plane ot' the shingle layers in a suitable. treating liquid lo permit said liquid to enter the ercvices l'ormed by the transverse laminations and draining th(` excess liquid 'lrom the bundle and siibsequentlyY rotating said bundle with the shingle layers in a planel at right angles to the greater length ot the bundle lo unilormly distribute the liquid along the surt'aee oi' the shingles in contact in the bundles and to expel the said liquid therefrom.'

3. lh'e method ot' treating shingles in the original eompaet bundle consisting in applying to the bundle a .suitable coating and in causing .said coating to penetrate in the in-v ter-slices between the transverse laminations,

ol the bundle and in subsequently rotating said bundle in the plane oi' the shingle layers to uniformly distribute the liquid along the surfaces ol the shingles in Contact in the bundle and to expel the excess liquid therel rom.

ln testimony whereof l alix my signature in presencev of two witnesses.
